摘要

本文研究了在氮气气氛中产生的压缩等离子体流作用下，铜原子合金Ti-6Al-4V表层的组织、物相、元素组成和显微硬度。结果表明：随着合金表层吸收能量密度在26 ~ 43 J/cm2范围内的增大，合金层中铜的浓度从20%下降到4%；厚度约为18 μm的合金层中含有CuTi2和Cu3Ti2金属间化物。合金层表面形成氮化物δTiN。750°С退火导致Cu3Ti2分解。

Structural-Phase State of the Surface Layer of Titanium Alloy Doped with Copper Atoms and Its Thermal Stability

Results of structure, phase and element composition, and microhardness of the surface layer of Ti–6Al–4V alloyed by copper atoms under the action of compression plasma flows generated in nitrogen atmosphere are presented in this work. The findings showed that growth of the energy density absorbed by the surface layer in the region of 26–43 J/cm² led to diminishing of copper concentration from 20 to 4 at % in the alloyed layer. An alloyed layer with thickness of ~18 μm contained CuTi₂ and Cu₃Ti₂ intermetallides. Nitride δTiN was formed on the surface of the alloyed layer. Annealing at 750°С resulted in Cu₃Ti₂ decomposition.
